Re: auditory hemi-neglect



It was in commisurotomized subjects, rather than in those with auditory
hemi-neglect, but we found results similar to Deouell, Deutsch, Scabini,
Soroker and Knight, using another dichotic pitch effect.

by normal and commisurotomized human subjects. Cortex 13: 137-149.

Dear Peter, Dennis et al,

You might be interested in our recently published article:

The study used the scale illusion:

I'd be happy to send a PDF to anyone who's interested.

Cheers,

Diana

Hello Everyone:

This is a followup to Peter Lennox's post of this morning, which prompted the question of whether there is significant evidence for auditory hemi-neglect. There are some older case studies which describe what might be an auditory analog of visual hemi-neglect. See, for example, KM Heilman & E Valenstein (1972, Auditory neglect in man. Arch Neurol., 26: 32-35). Apparently, work on the topic is ongoing. See L Spierer et al. (2007, Extinction of auditory stimuli in hemineglect: Space versus ear. Neuropsychologia, 45: 540-551). I hope that this helps. Kind wishes,

Dennis
